Abstract: A switch assembly (1) for switching electric circuits comprises a contributory switch (3), a main switch (2), and a flexible element (4). The contributory switch (3) and the main switch (2) are connected electrically in series, the contributory switch (3) and the main switch (4) each comprise at least one movable contact and the flexible element is connected to one movable contact of the contributory switch, a first contact (5a), and one movable contact of the main switch, a second contact (6a).

Abstract: A combination of a handle and a strap of a ski pole, the strap adapted to be between a hand of a person and the handle, and the combination allowing a quick uncoupling/re-coupling of the strap with the hand from/to the pole handle. The handle includes a handle body fixed on the pole, a locking base fixed in the body, a slide movable in respect to the body and locking base, an unlock lever communicating with the slide while shifted in respect to the body; and a pin having a first end with a widening and a second end fixing the pin to the strap in a predetermined area thereof. The strap is shaped to enclose by contact and extend around a palm and a wrist and between a thumb and forefinger by tightening. The predetermined area of the strap is centrally within the strap, between the thumb and forefinger.
